• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

OIL INJECTION OIL???? WHAT THE SAFEST?

I know this isnt husky related but im picking up a 71 dt250 and its oil injected. I was thinking about using reg two stroke like yamalube but ive heard the viscosity is thicker. maxima m is supposed to be good.

What oil injection oil do you recommend???

please give me some guidance so i dont burn this old gem up. Thanks
 
Just make sure that the oil you use is labeled for use in oil injector systems. It will be the right viscosity for the job. Most two stroke oils have a stoddard solvent or something of that nature added into the mix as a dispersing agent, and those blended for injector systems say so right on the bottle. Yamalube makes a blend called 2-S that is formulated for injector systems.
 
I have use the Belray S7 (I think) with great results. But then everything I have owned with oil injection, I have removed it to run premix. Much better results and engine life with premix. Cam.

How much pain is it to remove or disconnect oil injection?

Thanks for your input. now im hearing i should just bypass injector system and go straight premix.
 
My injector has worked perfectly for the last 5000 miles and its been run wide open quite a bit. I've been using some inexpensive suzuki 2 oil. On a 97 KE 100.
 
The reason many guys will remove the oil injection and run premix is that it is foolproof.
The injection system can fail - hard to say how likely that is, but you are talking about a 40 year old precision device that has probably had zero maintenance.
The operator can forget to check the injection oil level & run it dry :mad: (been there, done that)
Premix is the most simple and foolproof, i.e. the safest.
It also removes a small amount of weight...
You certainly do not HAVE to do it that way.
I rode a 2012 GasGas a couple weeks ago; it was pre-mix.
Probably good reasons for this.
As to what brand oil is best; any well known brand name will do.
 
Fasteer thanks. Now next question. If the bike i just bought.. (one w/oil injection) has been sitting 12 years, will the oil in the injection system go bad? probably be best to drain and add ndw syn 2 banger oil just as ghte said
 
Oil doesn't really go bad, however there is a possibility that it has been contaminated.
If the storage conditions allowed temperature swings it may have accumulated some water condensation, especially if the tank wasn't full.
You probably don't know what oil is in there, could be anything.
Personally, I would drain it and start with fresh (if you don't scrap the injection and go with premix)
 
Yamahas are pretty easy to remove the injection from. The throttle cable has a Y in the middle with the 2nd part going to the oil pump. The oil pump has a small hose that goes to the side of the carb to pump oil into the engine. It is simple to remove the oil tank and lines, disconnect the cable and plug the tiny hose spigot on the side of the carb with a vacuum cap (avail at any autopart store). I even did this with my kids PW50 and PW80 so we could all run the same premix. I use 50:1 Belray MC-1 in my racebike so just used that in the 50 and 80, with excellent results. Hope this helps.

Its very rare but I have had an oil pump stop working once. RD350LC. Expensive.
 
I've been using valvoline 2-stroke oil from NAPA. Has a picture of a lawnmower on the bottle.

There's two kinds. Read the back lable for air-cooled & injector engines.

Leave the injector & oil pump on there. They last forever.

14,000 on my RT1 360 with no oil issues.

Yamalube is good too.
